Method for diagnosis of components inside turbine generator

Abstract

A method for diagnosis of components inside a turbine generator includes collecting and measuring organic substances present in a gas inside the turbine generator to obtain data (first data). Before the collecting, organic substances generated from each component inside the turbine generator due to heat, discharge, corrosion, or friction, are measured to compile data (second data). The first data is compared to the second data to determine whether the first data includes the same data as in the second data to detect deterioration of the components inside the turbine generator.

What is claimed is:  
     
       1. A method for diagnosis of components inside a turbine generator, comprising: 
       collecting organic substances present in a gas inside a turbine generator;  
       measuring the organic substances collected to obtain first data for the organic substances;  
       measuring, before the collecting, organic substances generated from each component inside the turbine generator due to heat, discharge, corrosion, or friction, to compile second data for the organic substances; and  
       comparing the first data to the second data to determine whether data in the second data is present in the first data.  
     
     
       2. The method for diagnosis of components inside a turbine generator as claimed in claim  1  comprising detecting changes over time in data in the first data that is also present in the second data. 
     
     
       3. The method for diagnosis of components inside a turbine generator as claimed in claim  1  comprising identifying a component undergoing deterioration, or determining the cause of deterioration of the component, on the basis of data in the first data that is also present in the second data. 
     
     
       4. The method for diagnosis of components inside a turbine generator as claimed in claim  1 , including obtaining the first data and the second data by one of gas chromatography, infrared absorption spectroscopy, reflection infrared spectroscopy, mass spectrometry, and X-ray photoelectron spectroscopy. 
     
     
       5. The method for diagnosis of components inside a turbine generator as claimed in claim  1 , including using a computer for the comparing of the first data to the second data. 
     
     
       6. The method for diagnosis of components inside a turbine generator as claimed in claim  1 , wherein only data on aromatic hydrocarbons with a molecular weight of 92 or more among the first data and the second data are used as a standard for judgment in the comparing. 
     
     
       7. The method for diagnosis of components inside a turbine generator as claimed in claim  1 , including passing the gas withdrawn from the turbine generator through an adsorbent to collect the organic substances in the gas inside the turbine generator.
